Abstract：In order to solve the problem of phase ambiguity in the parameter estimation of Ultra -Wideband Radar signal , a method based on the resolving phase ambiguity technology of staggered PRI in ultra -wideband Radar is proposed .This method provides a better solution to the contradiction between phase ambiguity and pa -rameter estimation accuracy , which can realize the higher accuracy of signal parameter under the condition of low signal to noise ratio .Under the condition of gaussian white noise comparison of the narrowband LFM signal and the ultra-wideband LFM signal is analyzed theoretically and simulated .This method has proved effective .
